# \[PATCH RFT\] powerpc: dma-mapping: support debug\_dma\_mapping\_error - From: Shuah Khan \ - Date: 2012-10-26 00:16:37 - List: linuxppc-dev - Page: https://ratatoskr.run/linuxppc-dev/2012/10/3946195 - Thread: https://ratatoskr.run/linuxppc-dev/2012/10/3946195/t.md ```text Add support for debug_dma_mapping_error() call to avoid warning from debug_dma_unmap() interface when it checks for mapping error checked status. Without this patch, device driver failed to check map error warning is generated.
